Future Developments in Modeling and Monitoring of Volcanic Ash Clouds



[1] IAVCEI-WMO Workshop on Ash Dispersal Forecast and Civil Aviation; Geneva, Switzerland, 18–20 October 2010; The April–May 2010 Eyjafjallajökull eruption brought to light the harmful effects of volcanic ash on civil aviation and the importance of robust ash forecasting based on the combination of numerical weather prediction (NWP), volcanic ash transport and dispersal models (VATDMs), and data acquisition. The Workshop on Ash Dispersal Forecast and Civil Aviation has produced a consensual document describing the characteristics and range of application of different VATDMs, identifying the needs of the modeling community, investigating new data acquisition strategies, and discussing how to improve communication between the volcanology community and operational agencies. The workshop was held at the World Meteorological Organization's (WMO) Geneva headquarters under the sponsorship of the Faculty of Sciences of the University of Geneva, the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI), and the canton of Geneva and was organized by scientists from the University of Geneva (Switzerland), the Barcelona Supercomputing Center (Spain), the Aeronautical Meteorology Division of the WMO, and the British Geological Survey (United Kingdom). Fifty-two volcanologists, meteorologists, atmospheric dispersion modelers, and space- and ground-based monitoring specialists from 12 different countries were gathered (attendance was by invitation only), including representatives from six Volcanic Ash Advisory Centers (VAACs) and related institutions.
